Method of Transmitting Data

1. A data transmission method, which comprises the steps of: transmitting data over a first transmission channel; delaying the data transmitted over a first transmission channel and transmitting the delayed data over a second transmission channel; receiving the data transmitted over the first transmission channel and the data transmitted over the second transmission channel; delaying the data received over the first transmission channel; and checking whether the delayed data received over the first transmission channel and the delayed data transmitted over the second transmission channel correspond to one another.

2. The data transmission method according to claim 1 , wherein the transmitting step comprises selectively transmitting the data to be transmitted and data corresponding to the data to be transmitted.

3. The data transmission method according to claim 1 , which comprises differently coding the data transmitted with a time offset over the first transmission channel and over the second transmission channel.

4. The data transmission method according to claim 1 , wherein the transmitting step comprises transmitting the data to be transmitted themselves over one of the transmission channels and transmitting data corresponding to the data to be transmitted over the other transmission channel.

5. The data transmission method according to claim 1 , wherein the data transmitted over the first transmission channel are inverted relative to the data transmitted over the second transmission channel.

6. A data transmission method, which comprises the steps of: providing a data signal simultaneously to a first inverter and to a first time delay element; simultaneously transmitting the output of the first inverter over a first transmission channel and the output of the first time delay element over a second channel; receiving the data transmitted over the first transmission channel and the data transmitted over the second transmission channel; providing the data received over the first transmission channel to a second delay element; providing the data received over the second transmission channel to a second inverter; and checking whether the output of the second delay element and the output of the second inverter correspond to one another.
